BSOD - Driver IRQL not less or equal - 0x000000D1 - KMXCF.SYS

Hi, I'm a very new user of this forum and haven't posted before, but
here goes (fingers crossed I get it right!) ....


I have a Toshiba Satellite Pro Laptop running Vista Business (SP1) &
M/S Office 2003. I have just started to get the following problem which
seems to occur when email starts to be downloaded, Outlook downloads the
first 5 or so the I get a 'blue screen of death', with the following
text - *Driver_IRQL_not_less_or_equal*

*STOP: 0x000000D1 (0x87800000, 0x00000002, 0x00000000,
0xA7F44970)*

*KmxCF.sys - Address A7F44970 base at A7F32000, Datestamp
47171068*
I had to photograph the BSOD to get this information becuase it whizzed
through it's physical memory dump in less than 3 seconds! Once the
machine is re-booted I can access Control Panel, Hard Disks, Printers &
some applications but as soon as I try to receive email (outlook 2003)
or connect to the internet it crashes - joy!
I've surfed to try and find some answers and come up with ideas but
nothing which is exactly the same as my error and no suggestions as to
how to fix this. One thread has suggested CA Security is the problem
(KmxCF.sys file) and yes, I'm running CA Security Suite 2008. I have
used this to run a virus and trojen check and come up with zero
problems, I have also checked for updates and mine is totally up to
date, as well as checking their site for details (none, as expected from
the CA site, they are useless at helping solve problems!)

Please, please can anyone help me - I'm now on the 8th BSOD today and
can't get to important work emails which I need to reply to. Help, help,
help please :confused:

Thanks

Sally

Have you tried uninstalling CA?

SallyW67,
If you Safe Boot, does the problem still exist?

If no, then using the Startup tab of MSCONFIG.EXE, uncheck (you can always
check them again-they won't disappear from the list) everything that is not
from MS or Toshiba.

System still work?

Go back to MSCONFIG and check one of the items you checked. Restart. Keep
repeating this process until you find an interfering program.

Thanks Wharf Rat, 'not yet' (was trying to avoid that if at all possible
as it was originally a real b****r to get to run on Vista in the first
place!).
I have tried disabling the 'virus' part and the 'firewall' part and by
doing that I'm able to access and receive emails for 10 minutes (wow)
until it DSOD again.
I think I'll have to 'uninstall' totally
Thanks again

The fact that it was a "real b****r to get to run on Vista " should tell you
that it has issues and that you might be better served by a differet AV
solution. AVG and AVAST are both free for home users and well-liked in the
community.

Kevin - you are a star, thank you.
Did as you suggested as well as going into Device Manager and under
'non plug n play drivers' changed the properties of the file in
'startup' type to "demand"
Hey presto -I have mail!
Thank you for your help
